I have not been receiving emails. Senders are not blocked, they get a message saying that the server is rejecting their emails. These are contacts on my safe senders list who I have previously received emails from. Storage is fine. Reset my account, checked server, have done everything on the suggested list. Some emails are getting through eg. retailers but not most eg. Facebook code verification, personal emails.

Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
If email is rejected due to SPF fail, it means the Microsoft checked the senderr domain's SPF (Sender Policy Framework) DNS record, and saw that the server sender used to send the email from was not authorized to send mail on behalf of their domain.
This is not what you can fix. They need to fix on their end to make sure they have the correct SPF DNS record.
Thank you so much! I've been spending so much time at my end trying to resolve this so good to know it's not something I've missed! Much appreciated, thanks again :)
Oh sorry, this rejection email says Spf=Fail , Dkim=Pass , DMARC=Pass
Jana, this is not the full message for the error email.
Yes, your understanding is correct, the problem lies with the sender's domain, and it’s their responsibility to fix it.
But because it doesn't include the complete error message, I cannot tell what is not fixed.
To prevent email spoofing, email providers like Microsoft use protections like SPF (to define which servers are allowed to send on your behalf), DKIM (to attach a digital signature to prove the email is real), and DMARC (to tell other servers what to do if a message fails these checks). If a spoofed email fails these checks, it will usually be flagged as spam or rejected. In the rejection email, it typically would say if SPF, DKIM or DMARC check passes or fails, but since the message isn't complete, I cannot tell which one failed.
As for others, without seeing the rejection email, I wouldn't be able to tell you the precise reason why it has been rejected.
Microsoft email users are targets of spam/scam and hackers. This is why Microsoft implements very strict email protocols like the requirement of SPF, DKIM and DMARC from other senders' domains.
I have the rejection email, "Access denied, sending domain TELUSPLANET.NET (not just Telus, I have other senders with other providers who couldn't send) doesn't meet the required authentication level. The sender's domain in the 5322.From address doesn't meet the authentication requirements defined for the sender, To learn how to fix this issue see: https://go.microsoft.com/fwlink/p/?linkid=2319303 " So if I understand the explanation it is up to the sender to go through these steps? This particular person sends a lot of large emails but why have many emails from other senders been rejected at the same time?
